Upsets continue at the Rio 2016 Olympic Games table tennis event as Nigeria’s Aruna Quadri defeated former world number one and current world number 13 Timo Boll in the Men’s Singles Round of 16.

With this victory, the 27-year-old Nigerian becomes the first ever African Olympic quarter-finalist in the sport of table tennis, making it the perfect birthday gift for the impressive player who celebrates his 28th birthday on August 9.

Aruna raced to a 3-0 lead and looked like an unstoppable force for most of the match.

A comeback was on the cards as Boll, who was a favorite for a medal here in Rio, fought back to 3-2, taking the fourth and fifth games in comfortable fashion. But it was a case of too little too late.

Aruna held his nerve and used his unique brand of athletic shot making to take the sixth game 11-9 and win the match.

“This is amazing! I don’t know what to say. My fans made me do this. Thank you for all the Brazilian spectators for their support. They gave me so much energy. This feels so good, it is a dream come true that I am in the quarterfinals,” said the world number 40 after his spectacular win.

Boll, who had the honor of carrying the German flag in the Opening Ceremony, once again had to reflect on an early Olympic exit: “He has surprised a lot of people. I knew he was good coming into the match. I just have to say well played! His whole game is different, so it took me awhile to work it out. Once I was 0-3 down I started to get more into the match, but it was already too late.”

Close to making the biggest upset in table tennis history to challenge Chinese dominance, Korea Republic’s Jeong Youngsik started his fourth round encounter against the current World Champion Ma Long of China with a 2-0 lead, but the world number one was quick to recover from his losses to prevail 4-2.

Aruna Quadri will face Ma Long in the Quarter-final. The match will be played by 9:30pm Brazilian time.
